    Product Description

    KEOLL Portable Charger Power Bank with Built-in USB-C Cable

    power bank

    IMPORTANT: 40000mAh Power Bank is NOT allowed on a plane.

    How to charge this portable phone charger?

    1. Plug the built-in C cable into an adapter (not included) to charge the power bank.

    2. Use the included USB-A to USB-C charging cable: Plug the C end into the Type-C input port of the power bank, and plug the A end into the adapter (not included).

    The number not moving up when charging the power bank.

    First, use a power bank to charge your device to drain the remaining power of the power bank.

    Then, recharge the power bank to 100% without interruption.

    Why doesn't my portable power bank display the fast charging icon during the charging process?

    1. Make sure your electronic device, charging cable, and adapter support fast charging.

    2. When the device has enough power, the portable charger will enter "trickle mode" to protect the device and the fast charging icon will no longer be displayed.

    The built-in USB-C cable can charge my iPhone 16?

    Yes, you can use the built-in cable to charge your iPhone 15/16 series, as well as other USB-C-enabled devices.

    • Reviewed in the United States on November 16, 2024
      Bought this skeptical of the claimed capacity, but I've been pleasantly surprised. I haven't managed to run the pack's charge down much below 50% because it takes so long! I was able to charge up my phone 3x, a tablet and 4 sets of Bluetooth headphones (collectively 15-18k mAh) and it had plenty of capacity. I will be able to use this for camping trips as it's pretty compact. The light was underwhelming, but it's a nice bonus and will be very usable to read by or small night tasks like searching for something, avoiding trip hazards while walking, etc

      One thing to keep on mind- the downside of all this capacity is that it takes a long time to charge with your usual 2A USB wall charger.

      Looks and feels like a quality product at a favorable cost. For me, the shape is important. This portable charger is longer and slimmer than others of similar capacity. This allows the charger to fit perfectly in one of the slim compartments in my shoulder bag. It has connections for USB A and C which is perfect for my use. It also has a built-in USB-C cable for charging and powering connected devices and is designed to allow it to be used as a carrying strap for portability. If you need to use it for devices that require other connections such as micro USB or Lightning, you may need to consider purchasing cables or adapters to meet your requirements. These comments are based on my limited use so far, but overall, my impressions are very favorable.

      So far I have been happy with how fast this charger charges my phone. I like that is has a built in usb c cable PLUS a usb a and usb c port. It is much heavier than the other smallish power bank I have, and so far has held a charge well. and it feels substantial. Great for a backpack, but too big for a pocket, and kinda heavy unless you have a bigger purse. but it feels well made, and charges my phone fast. the price of around $24 was good for the value....but I kept seeing this pretty consistent cheap sale price and the $99 one that seems to be marketed as the same. so I started researching

      I was under the impression that I was getting a sale price of $24ish off of the regular $99 price as when you toggle between the two items it looks like just different colors and both say "Portable Charger 40000mAh Power Bank, 22.5W Fast Charging Battery Pack with Built-in USB C in & out Cable." etc - the write up below it seems slightly different, but not substantially. But when I looked at the details there are 2 model #s and this one came out in April 2024, the other came out in Aug 2024.

      B0D2TVCNSL "Upgraded Two-Way Fast Charging USB-C Power Bank:"
      B0DD3V5528 "Upgraded Cable&Port Bi-directional in/out Power Bank:"
      doesn't seem too diffferent - but why the lower price

      But the main description at the top makes it seem like they are exactly the same

      When I asked Rufus AI "what's the difference between model #B0D2TVCNSL (that's this one at $24ish) and B0DD3V5528 (the $99 one)" it said: "The B0D2TVCNSL model has a capacity of 30,000mAh, while the B0DD3V5528 model has a higher capacity of 40,000mAh. This means the 40,000mAh model can provide more charges to devices before needing to be recharged itself.

      In terms of charging speed, both support fast charging but at different rates. The B0D2TVCNSL provides up to 20W fast charging, while the B0DD3V5528 offers a faster 22.5W fast charging speed. plus the color difference." I'm wondering what other differences there are and are they 2 different products - rather than one with a permanent sale on?"

      For the price, and so far I am pretty happy, but if the Rufus AI is accurate, I feel like the description should be clearer that this one is an earlier 30,000 mAh etc. feels kinda bait and switchy? But I and Rufus could be wrong.

      But so far it is working well for me. If a 40000 mAh is important to you -maybe reach out to the company and confirm.

      Portable Charger Review:

      This portable charger has been a lifesaver on busy days when I’m constantly on the go. The compact, lightweight design makes it easy to slip into my bag without taking up much space, yet it holds an impressive charge capacity. I can fully charge my phone a couple of times before needing to recharge the device itself, which is perfect for long days or trips.

      The charging speed is quick, and the indicator lights make it easy to check the remaining battery level. It’s also user-friendly, with a simple plug-and-go design that makes charging straightforward. Plus, the build feels sturdy, so I’m confident it will last a long time.

      If you’re looking for a reliable, portable power source that won’t weigh you down, I highly recommend this one!

      This is an excellent powerful charger. It's perfect for those who want large capacity charging without a useless solar panel found on so many models.
      This has no problem charging my phone from half to full about a dozen times.
      The built-in usb-c charging cable eliminates you from having to carry one but you can attach cables to charge multiple devices.
      This is very well made and not too heavy for the capacity.
      I have a 60 watt folding solar charger that can charge this from zero to full capacity in about 8 hours or so will good sunshine.
      Highly recommend this charger. Can't beat it for the price.

      This portable charger works with I phones and Samsung phones. It has a built in USB C, in and out cable and has lots of power. I have charged my I phone, I pad and even my Mac Book and it still has power to go. Slim design makes this a very easy charger to travel with or just daily use. Charges fast so now I do not need to worry about losing power when using my electronics.
